Description

Method and apparatus for assisting radio access technology self-organizing network configuration

This patent application claims to be a non-provisional application No. 14/514,776 entitled "METHODS AND APPARATUS FOR ASSISTED RADIO ACCESS TECHNOLOGY SELF-ORGANIZING NETWORK CONFIGURATION", filed on October 15, 2014, and April 4, 2014 The priority of the provisional application No. 61/975,574, entitled "METHODS AND APPARATUS FOR ASSISTED RADIO ACCESS TECHNOLOGY SELF-ORGANIZING NETWORK CONFIGURATION", which has been assigned to the assignee of the case, This is explicitly incorporated herein by reference.

Broadly stated, aspects of the present invention relate to wireless communications, and more particularly to aspects and apparatus for assisting wireless access technology in ad hoc network configuration.

Wireless communication networks have been widely deployed to provide various communication services such as voice, video, packet data, messaging, and broadcasting. These wireless networks can be multiplexed networks that can support multiple users via shared available network resources. Examples of the multiplex network include a code division multiplex access (CDMA) network, a time division multiplex access (TDMA) network, a frequency division multiplex access (FDMA) network, and orthogonal FDMA (OFDMA). Network and single carrier FDMA (SC-FDMA) networks.

The wireless communication network can include multiple evolved Node Bs (eNodeBs) that can support communication for multiple User Equipments (UEs). The UE can communicate with the eNodeB via the downlink and uplink. The downlink (or forward link) refers to the communication link from the eNodeB to the UE, and the uplink (or reverse link) refers to the communication link from the eNodeB to the base station.

In some wireless communication networks, a User Equipment (UE) selects a base station and maintains a connection with the base station, wherein the base station provides communication capabilities for the UE. In addition, in these wireless communication systems, small cells are deployed to improve wireless network communication when subjected to poor base station (e.g., home Node B) connections. In these wireless communication networks, the inefficient use of available communication resources (especially identification resources for cell configuration) may result in reduced performance of wireless communication. Even the aforementioned inefficient resource utilization makes it impossible for network devices to achieve higher wireless communication quality. Having understood the above, it should be understood that there are significant problems and disadvantages associated with current ad hoc network configurations.

In order to achieve the foregoing and related ends, one or more aspects include the features specifically described in the following detailed description and claims. Certain exemplary features of one or more aspects are described in detail in the following description and drawings. However, these features are merely illustrative of some of the various ways in which the basic principles of these various aspects may be employed, and the description is intended to include all such aspects and their equivalents.

The specific embodiments described below in connection with the drawings are merely intended to describe various configurations, and are not intended to represent the concepts described in the embodiments. In order to have a thorough understanding of the various concepts, the specific embodiments include specific details. However, it will be apparent to those skilled in the art <RTIgt; In some instances, well known elements are shown in block diagram form in order to avoid obscuring the concepts. In one aspect, the term "element" as used in this context may be one of the components that make up a system, which may be a hardware or a soft body, and may be divided into other components.

The techniques described herein can be used in a variety of wireless communication networks and systems such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and other networks. The terms "network" and "system" are usually used interchangeably. A CDMA network may implement wireless technologies such as Universal Terrestrial Radio Access (UTRA), CDMA2000, and the like. UTRA includes variants of Wideband CDMA (WCDMA) and other CDMA. CDMA2000 covers the IS-2000, IS-95 and IS-856 standards. A TDMA network can implement wireless technologies such as the Global System for Mobile Communications (GSM). The OFDMA network can implement wireless technologies such as evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, and the like. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and Improved LTE (LTE-A) are new releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The techniques described in this disclosure can be applied to the wireless networks and wireless technologies mentioned above as well as other wireless networks and wireless technologies. For clarity of explanation, certain aspects of these techniques are described below for LTE, and LTE terminology is used in much of the description below.

Aspects of the invention generally involve the use of a wireless local area network (WLAN) to assist in configuring a wireless wide area network (WAN or WWAN) ad hoc network (SON). SON simplifies and automates the initial configuration of the implementation and maintenance of the mobile network. However, in some wireless communication systems, the SON entity of the WAN configuration deployed in a dense communication environment may experience some difficulties in obtaining a large number of measurements for SON. For example, a WAN entity such as a small cell that communicates over Long Term Evolution (LTE) may find it difficult to obtain some measurement information from a User Equipment (UE).

In particular, in a dense communication environment that includes a large number of small cells, a WAN entity at a small cell (eg, associated with LTE SON / for LTE SON) can be used with one or more adjacent small cells The WAN entities operate on the same or similar time/frequency characteristics. Thus, such a dense communication environment may present a higher level of interference due to pilot-frequency contamination of, for example, a WAN entity of one or more small cells. For example, if there are more than two cells (except for the strongest cells) at a certain frequency of the strongest cells, there is a pilot frequency contamination. Therefore, the UE is not able to obtain reliable measurement information for subsequent transmissions to the WAN entity (eg, LTE SON). Even in multi-radio access technology (RAT) small cell deployments using collocated WAN and WLAN (eg, Wi-Fi) entities, the WLAN entity is capable of transmitting measurement information to the UE and receiving measurement information from the UE, However, this information, which is particularly useful for interference management and/or SON purposes for WAN entities, is also ignored for such purposes.

Thus, in some aspects, the method and apparatus of the present invention can provide an efficient and efficient solution for providing WLAN-assisted WAN SON entities at one or more small cells employing collocated WLAN and WAN entities. In one aspect, the apparatus and method of the present invention can provide an auxiliary WAN SON solution by receiving measurement information from the UE using a collocated WLAN entity. The measurement information may correspond to or indicate a UE measurement of one or more WLAN communication characteristics. For example, a WLAN entity can transmit a beacon signal/indication to assist in WLAN positioning and connection. The UE may measure the beacon signal/indicated signal strength metric (eg, but not limited to Received Signal Strength Indicator (RSSI)) to determine other communication characteristics, such as path loss between the WLAN entity and the UE.

For example, due to strong interference from WAN entities of other small cells using the same or similar time and/or frequency resources, the UE is not able to directly detect WAN entities of small cells. In addition, the UE can easily detect the WLAN entity at the small cell that is collocated with the WAN entity, since the WLAN entity can operate in an unlicensed frequency band with multiple frequencies that help reduce interference. In addition, the WLAN Media Access Control (MAC) entity may use Carrier Sense Multiple Access (CSMA), which may implement the first listening mode to reduce the probability of collision between WLAN entities.

Additionally, aspects of the invention may include WLAN entities embedding RAT entity-specific information in one or more beacon indications, such as, but not limited to, WAN entity load levels Value, number of UEs served, quality of service information, carrier type information, scheduling information, priority level information, allowable interference level values, coexistence parameters such as power backoff, time division multiplexing (TDM) And/or a frequency division multiplexing (FDM) configuration, a partial frequency reuse configuration, and one or more action related parameters. The RAT entity-specific information can be used for interference management, mobility management, and/or self-organization of the WAN SON entity (eg, transmit power adjustment and/or resource adjustment).

In other words, aspects of the present invention may embed RAT entity-specific information corresponding to or related to a second RAT entity (e.g., a WAN entity) in a first RAT entity beacon. Therefore, the UE can instead provide corresponding measurement information for subsequent WAN SON entity assisted decision. In other aspects, a WLAN entity of an adjacent small cell can detect measurement information of the WLAN entity of the small cell (which is responsible for embedding information specific to the RAT entity) and provide the WLAN entity to the small cell. In particular, in one example, the path loss of the WAN entity can be determined based at least in part on the path loss and the correction factor value of the first RAT entity (eg, a WLAN entity). In these aspects, the correction factor value can be at least dependent on the frequency of the second RAT entity (e.g., WAN entity). Accordingly, the apparatus and method of the present invention provides a WLAN-assisted solution for assisting interference management at a second RAT entity in a dense small cell environment.

1 is a block diagram conceptually showing an example of a telecommunications network system 100 in accordance with an aspect of the present invention. The telecommunications network system 100 can include one or more network entities 110 (e.g., one or more small cells). As used herein, the term "small cell" may represent a corresponding coverage area of an access point or access point, where in this case, for example, with a macro network access point or a macro set cell's transmit power or coverage area In contrast, the access point has a relatively low transmit power or a relatively small coverage area.

For example, macrocells can cover a relatively large geographic area, such as, but not limited to, a few kilometers in radius. In contrast, small cells can cover a relatively small geographic area, such as, but not limited to, a single floor of a house, building, or building. Thus, small cells may include, but are not limited to, such as a base station (BS), an access point, a femto node, a femto cell, a pico node, a micro node, a Node B, an evolved Node B (eNB), a home Node B ( HNB) or a device such as Home Evolution Node B (HeNB). Thus, the term "small cell" as used herein refers to a relatively low emission power and/or a relatively small coverage area cell as compared to a macro cell.

Each small cell 110 (eg, small cell 110y) can include a SON element 130 that can be configured to autonomously manage interference that occurs due to signals from two or more small cells. Further, for example, SON element 130 (which may be included in each of the small cells 110 shown in FIG. 1) may be configured to receive measurement information at the first RAT entity. In other words, SON element 130 can be configured to manage interference at a second RAT entity (e.g., WAN entity 138) based on measurement information received by a first RAT entity (e.g., WLAN entity 136). Such interference management can be accomplished via one or both of the first management element 132 and the second management element 134.

Additionally, the small cell 110y can be configured to facilitate communication with the network via two or more wireless RAT protocols. In other words, the small cell 110y can be configured to include the first RAT entity in the form of a WLAN entity 136 and the second RAT entity in the form of a WAN entity 138. Thus, in some aspects, the small cells 110y can communicate according to a variety of RAT protocols. In some aspects, WAN entity 138 can include a radio that communicates in accordance with at least one technique, such as, but not limited to, Long Term Evolution (LTE), Universal Mobile Telecommunications System (UMTS), and Code Division Multiple Access (CDMA) 2000. . In an additional aspect, WLAN entity 136 can include a radio that communicates in accordance with at least one technique, such as, but not limited to, Wi-Fi.

Moreover, one or both of the WLAN entity 136 and the WAN entity 138 can be configured to perform an autonomous function in accordance with the SON mechanism. For example, WAN entity 138 may alternatively be referred to as WAN SON entity 138, which may be configured to self-organize according to a decentralized, centralized, and/or hybrid architecture. In some aspects, WAN entity 138 may alternatively be referred to as a WLAN-assisted WAN SON entity 138. Moreover, WAN entity 138 can be configured to operate in accordance with one or more of a self-configuring function, a self-optimizing function, and a self-recovering function, all of which enable WAN entity 138 to plan in an autonomous and efficient manner, Configuration, management, optimization, and recovery.

Referring to the first management component 132, an aspect thereof can include: configured to manage interference at a second RAT entity (e.g., WAN entity 138) based on measurement information received by a first RAT entity (e.g., WLAN entity 136) Various components and/or subcomponents. In particular, in these aspects, the first management element 132 can be configured to: at the first RAT entity (eg, the WLAN entity 136), receive measurement information from the UE 120y to assist the second RAT entity (eg, a WAN entity) Interference management at 138). For example, UE 120y may be in an environment that exhibits a high degree of pilot-frequency pollution such that it limits UE 120y from obtaining accurate measurement information associated with the second RAT entity.

In some aspects, SON component 130 and/or UE 120y may determine or identify that the environment exhibits a high degree of pilot frequency contamination via measurement component 140. Thus, in the case where the first RAT entity is collocated with the second RAT entity, ie, when the WLAN entity 136 is collocated with the WAN entity 138, the first RAT entity (or WLAN entity 136) may be configured to receive and process from the UE. The 120y measurement information is used to assist the WAN entity 138. In these aspects, although the WAN entity 138 can or is configured to obtain these measurements from the UE 120y, the environment can exclude the WAN entity 138 from receiving accurate results from the UE 120y.

For example, an empty interfacing plane corresponding to WAN entity 138 may not allow for embedding and transmitting RAT entity-specific information to UE 120y or another small cell (eg, small cell 110z). Thus, WLAN entity 136 (which may not experience poor or reduced communication quality with UE 120y or communication quality between UEs 120y) may receive more accurate measurements (eg, measurement information) from UE 120y. Additionally, the WAN entity 138 can be configured or configured to decide when to use or process the measurement information received from the WLAN entity 136. In these aspects, WLAN entity 136 can be configured to receive measurement information on a periodic basis.

In another aspect, the first management component 132 can be configured to arrange or configure the second RAT entity (eg, the WAN entity 138) based at least in part on the measurement information received by the first RAT entity (eg, the WLAN entity 136). . In particular, the measurement information can include a path loss value determined based at least in part on one or both of a signal strength value and a transmit power value of one or both of the first RAT entity and the second RAT entity. In some aspects, the signal strength value comprises a Received Signal Strength Indicator (RSSI) value. Accordingly, WLAN entity 136 and/or UE 120y may be configured to determine a second RAT entity (eg, WAN entity 138 based at least in part on a path loss value and a correction factor value of the first RAT entity (eg, WLAN entity 136). Path loss value. In these aspects, the correction factor value may depend at least on the frequency and/or frequency band of the second RAT entity (e.g., WAN entity 138). Additionally, the correction factor may include transmit power values and antenna gain values for one or both of WLAN entity 136 and WAN entity 138.

In an additional aspect, the first management element 132 can be configured to transmit a management indication using a first RAT entity (e.g., WLAN entity 136) to trigger the UE 120y to perform one or more quantities on or at the first RAT entity. Test to determine the measurement information. In other words, the WLAN radio of the small cell 110y may be configured to transmit a management indication in the form of a beacon indication to trigger the UE 120y to measure at least the signal strength (eg, RSSI) of the beacon indication or the beacon indication Corresponding signal strength. In these aspects, the beacon indication can be transmitted to the UE 120y periodically.

In these aspects, the beacon indication transmitted by WLAN entity 136 may alternatively be referred to as a beacon frame, which may have the type of management frame and be periodically transmitted to enable the WLAN entity and/or UE to have The way to establish and maintain communication. For example, the beacon frame may be a management frame in an IEEE 802.11-based WLAN, which may include information about the network. In some aspects, the beacon frame body can be located between the header and the Cyclic Redundancy Check (CRC) field and form the other half of the beacon frame.

Each beacon frame may carry or include information in the frame body, including but not limited to: time stamp, beacon interval, capability information, service set identifier (SSID), supported rate, frequency hopping ( FH) Parameter Set, Direct Sequence (DS) Parameter Set, Contention Free (CF) Parameter Set, IBSS Parameter Set, and Traffic Volume Indicator (TIM). For example, the beacon indication may include an SSID, eg, an SSID of another first RAT that is collocated with another second RAT.

Moreover, an aspect of the second management component 134 is described that can include configuring to manage interference at a second RAT (eg, WAN entity 138) based on measurement information received by the first RAT (eg, WLAN entity 136). Various components and/or subcomponents. In particular, in this aspect, the second management component 134 can be configured to: at the first RAT (eg, WLAN entity 136), receive from the UE 120y a transmission for triggering a management indication (eg, a probe response indication) Request indication (eg, probe request indication). In some aspects, the management indication may take the form of a probe request, or similar to a probe request, and the probe request may be used to actively seek for any or a particular access point or BSS (eg, WLAN entity 136). Additionally, the station parameters and supported data rates may be used to answer management instructions, and/or the management instructions may include at least some information associated with the beacon indications described herein.

Moreover, the second management component 134 can be configured to embed the RAT-specific information of the second RAT (e.g., WAN entity 138) in the management indication by the first RAT (e.g., WLAN entity 136). In these aspects, the first RAT and the second RAT may be collocated entities. Additionally, the second management component 134 can be configured to send the management indication to the UE 120y. In these aspects, the management indication may allow the UE 120y to obtain a measurement value similar to the transmitted management indication (e.g., beacon indication).

That is, the management indication may enable the UE 120y to obtain at least a corresponding signal strength value for path loss determination of one or both of the first RAT and the second RAT. In some aspects, the management indications can include the following or take the form of a probe response signal/indication, a beacon indication, or any broadcast indication, each of which is associated with a WLAN entity 136. In other aspects, the second RAT entity (e.g., WAN entity 138) can directly receive the measurement information associated with the transmission of the broadcast indication or receive via UE 120y.

In some aspects, the RAT entity-specific information of the second RAT may include one or more of the following: a load level value, a number of UEs served, quality of service information, and carrier type information. In some aspects, the carrier type information can include information relating to the number of carriers at the small cell, an indication of whether the small cell supports carrier aggregation for one or both of the WLAN entity 136 and the WAN entity 138, Whether the WAN entity 138 supports or communicates according to unlicensed spectrum technology, and the channels and/or frequency bands used by the small cell in one or both of the licensed spectrum and the unlicensed spectrum of the WAN entity 138. In an additional aspect, the second management component 134 can be configured to embed RAT-specific information in a reserved field of the probe response indication. Additionally, in other aspects, the RAT entity-specific information may include scheduling information for UEs of one or more services. In these aspects, the schedule information can include time and/or frequency resources. Further, the information specific to the RAT entity may include an indication that the UE is a cell edge UE or a cell center UE.

Referring to the measurement component 140 (which may be included, implemented, or embodied in the UE 120y), it is described that the measurement component 140 includes aspects of various components and/or sub-components configured to perform the following operations: based on the transmission to the The measurement information of a RAT (e.g., WLAN entity 136) assists in the management of interference at the second RAT (e.g., WAN entity 138). In particular, in these aspects, measurement component 140 can be configured to: measure a signal strength value corresponding to a management indication received from a first RAT (eg, WLAN entity 136) to assist a second RAT (eg, Interference management at WAN entity 138). Further, the metrology component 140 can be configured to transmit measurement information to the first RAT for configuration of the second RAT.

For example, the metrology component 140 can be configured to determine the first based at least in part on one or both of a signal strength value (eg, RSSI) and a transmit power value of one or both of the first RAT and the second RAT. The path loss value of the RAT (e.g., WLAN entity 136). Additionally, after obtaining and/or determining the path loss associated with the WLAN entity 136, the measurement component 140 can be configured to determine the second RAT based at least in part on the path loss value and the correction factor value of the first RAT entity The path loss value (e.g., WAN entity 138). In some aspects, the correction factor value can be at least dependent on the frequency of the second RAT entity.

In another aspect, the measurement information may include one or more of the following: a path loss value of the first RAT, a path loss value of the second RAT, a load level value, a number of UEs served, and a quality of service. Information and carrier type information. Thus, UE 120y may be configured to provide measurement information in addition to providing path loss values based on requests or instructions from WLAN entity 136. Moreover, the metrology component 140 can be configured to identify with the second RAT entity (eg, the WAN entity 138) based at least in part on one or both of the SSID or the basic service set identifier (BSSID) obtained from the management indication. A collocated first RAT entity (eg, WLAN entity 136). In some instances, the SSID can be configured to maintain packet information in the correct WLAN even when there is an overlapping WLAN. However, there are typically multiple access points in each WLAN, so there must be a way to identify these access points and their associated clients. Therefore, the BSSID can be included in all wireless packet information.

In some aspects, measurement component 140 can be configured to send a request indication (eg, a probe request indication) to a first RAT (eg, WLAN entity 136) to trigger transmission of the management indication. In these aspects, the management indication can include a probe response indication or a beacon indication. Additionally, to trigger a probe response for any and all desired collocated small cells, the metrology component 140 can be configured to transmit a probe request indication including one or both of an SSID or a BSSID.

For example, measurement component 140 can be configured to determine that a request indication transmission condition has been satisfied for triggering transmission of the request indication to WLAN entity 136. In other words, the UE 120y can determine via the metrology component 140 that the quality of communication with small cells (e.g., small cells 110y) with which they are actively connected has decreased. Specifically, the measuring component 140 may be configured to: determine, by one or more of the following, that the request indication transmission condition is met: determining that the channel quality indicator (CQI) value meets or falls below the CQI threshold, the bit The error rate (BER) value meets or exceeds the BER threshold, and the CQI backoff value meets or exceeds the CQI fallback threshold. Additionally, the request transmission condition can be determined based at least in part on Radio Link Failure (RLF) information, external rate loop control information, or some other action related information.

Moreover, for example, telecommunications network system 100 (FIG. 1) can be an LTE network or some other similar wireless wide area network or WWAN. In this LTE aspect, telecommunications network system 100 can include a plurality of eNodeBs 110 (each of which can include SON component 130), user equipment (UE) 120 including measurement component 140, and other network entities. The eNodeB 110 for macro cells may be referred to as a macro eNodeB. The eNodeB 110 for small cells may be referred to as a small eNodeB. In the example shown in FIG. 1, eNodeBs 110a, 110b, and 110c may be macro eNodeBs for macro cells 102a, 102b, and 102c, respectively. The eNodeBs 110x, 110y, and 102z may be small eNodeBs for small cells 102x, 102y, and 102z. The eNodeB 110 can provide communication coverage for one or more (eg, three) cells.

It should be understood that each of the eNodeBs may include a SON element 130. In some aspects, telecommunications network system 100 (FIG. 1) may include one or more relay stations 110r and 120r, which may also be referred to as relay eNodeBs, repeaters, and the like. Relay station 110r may be a transmission of data and/or other information from an upstream station (e.g., eNodeB 110 or UE 120) and transmit the received data and/or to a downstream station (e.g., UE 120 or eNodeB 110). The station for the transmission of other information. The relay station 120r may be a UE that relays transmissions for other UEs (not shown). In the example shown in FIG. 1, relay station 110r can communicate with eNodeB 110a and UE 120r to facilitate communication between eNodeB 110a and UE 120r.

Telecommunications network system 100 (FIG. 1) may be a heterogeneous network that includes different types of eNodeBs 110 (e.g., macro eNodeBs 110a-c, pico eNodeBs 110x, femto eNodeBs 110y-z, repeaters 110r, etc.). These different types of eNodeBs 110 may have different transmit power levels, different coverage areas, and have different effects on interference in the telecommunications network system 100. For example, macro eNodeBs 110a-c may have a higher transmit power level (eg, 20 watts), while pico eNodeB 110x, femto eNodeB 110y-z, and repeater 110r may have lower transmit power levels (eg, , 1 watt).

The telecommunications network system 100 can support synchronous or asynchronous jobs. For synchronous operation, the eNodeBs can have similar frame timing, with transmissions from different eNodeBs 110 being approximately aligned in time. For non-synchronous jobs, eNodeB 110 may have different frame timings, and transmissions from different eNodeBs 110 are not aligned in time. The techniques described herein can be used for both synchronous and asynchronous jobs.

Network controller 124 can be coupled to a set of eNodeBs 110 and provide coordination and control for these eNodeBs 110. Network controller 124 can communicate with eNodeB 110 via a loadback. The eNodeBs 110 can also communicate with each other, for example, directly or via indirect communication via wireless backhaul or wired backhaul (e.g., X2 interface) (not shown).

UEs 120 (e.g., 120x, 120y, etc.) may be dispersed throughout telecommunications network system 100, and each UE 120 may be stationary or mobile. For example, UE 120 may be referred to as a terminal, a mobile station, a subscriber unit, a station, and the like. In another example, the UE 120 can be a cellular telephone, a personal digital assistant (PDA), a wireless data modem, a wireless communication device, a handheld device, a laptop, a wireless telephone, a wireless area loop (WLL) station, a tablet device. , small notebooks, smart computers, and so on. UE 120 can communicate with macro eNodeBs 110a-c, pico eNodeBs 110x, femto eNodeBs 110y-z, repeaters 110r, and the like. For example, in FIG. 1, a solid line with double arrows indicates the desired transmission between the UE 120 and the serving eNodeB 110 (which is the eNodeB 110 that specifies the UE 120 to be served on the downlink and/or uplink). A dashed line with double arrows indicates interference transmission between the UE 120 and the eNodeB 110.

LTE can use orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as tones, bins, and the like. Each subcarrier can be modulated using data. Typically, modulation symbols are transmitted using OFDM in the frequency domain and modulation symbols are transmitted using SC-FDM in the time domain. The spacing between adjacent subcarriers may be fixed, and the total number of subcarriers (K) may be dependent on the system bandwidth. For example, the secondary carrier spacing may be 15 kHz, and the minimum resource configuration (which is referred to as a "resource block") may be 12 secondary carriers (or 180 kHz). Thus, for a system bandwidth of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal Fast Fourier Transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. In addition, the system bandwidth can also be divided into sub-bands. For example, a subband can cover 1.08 MHz (ie, 6 resource blocks), and system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz can exist 1, 2, 4, 8, or 16 times, respectively. frequency band.

7 is a block diagram 850 conceptually illustrating a downlink frame structure in a telecommunications system, in accordance with an aspect of the present invention. The transmission timeline for the downlink can be divided into units of radio frames. Each radio frame has a predetermined duration (eg, 10 milliseconds (ms)) and is divided into 10 sub-frames with indices 0 through 9. Each subframe can include two time slots. Therefore, each radio frame can include 20 time slots indexed from 0 to 19. Each time slot may include L symbol periods, for example, 7 symbol periods for a normal cyclic prefix (as shown in Figure 7) or 14 symbol periods (not shown) for extending a cyclic prefix. An index of 0 to 2L-1 can be assigned to 2L symbol periods in each subframe. The available time-frequency resources can be divided into resource blocks. Each resource block may cover N secondary carriers (eg, 12 secondary carriers) in one time slot.

In LTE, for example, an eNodeB may transmit a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) for each of the cells in the coverage area of the eNodeB. The primary synchronization signal (PSS) and the secondary synchronization signal (SSS) may be transmitted in symbol periods 6 and 5 in each of subframes 0 and 5 of each radio frame having a normal cyclic prefix, as shown in FIG. 6. Shown in . The UE can use these synchronization signals to achieve cell detection and cell capture. The eNodeB can transmit system information in a physical broadcast channel (PBCH) in symbol periods 0 to 3 in slot 1 of subframe 0.

The eNodeB may send a Physical Control Format Indicator Channel (PCFICH) in only a portion of the first symbol period of each subframe (but in Figure 6, described throughout the first symbol period). The PCFICH can transmit multiple symbol periods (M) for controlling the channel, where M can be equal to 1, 2 or 3 and can vary with the subframe. In addition, for small system bandwidths (eg, having less than 10 resource blocks), M can also be equal to four. In the example shown in Fig. 6, M = 3. The eNodeB may transmit an entity H-ARQ Indicator Channel (PHICH) and a Physical Downlink Control Channel (PDCCH) in the first M symbol periods (M=3) of each subframe. The PHICH can carry information for supporting hybrid automatic retransmission (H-ARQ). The PDCCH may carry information about the UE's uplink and downlink resource configurations and power control information for the uplink channel. Although not illustrated in the first symbol period in FIG. 6, it should be understood that the PDCCH and PHICH are also included in the first symbol period.

Similarly, PHICH and PDCCH are also included in the second and third symbol periods, but this is not illustrated in FIG. The eNodeB may send a Physical Downlink Shared Channel (PDSCH) in the remaining symbol periods of each subframe. The PDSCH may carry data for UEs scheduled for data transmission on the downlink. In 3GPP TS 36.211, titled "Evolved Universal Terrestrial Radio Access (E-UTRA); Physical Channels and Modulation," various signals and channels of LTE are described, where the file is publicly available.

The eNodeB can transmit PSS, SSS, and PBCH in the middle of the system bandwidth used by the eNodeB at 1.08 MHz. The eNodeB can transmit the PCFICH and PHICH channels in the entire system bandwidth for each symbol period in which the PCFICH and PHICH are transmitted. The eNodeB may send PDCCHs to some UE groups in certain portions of the system bandwidth. The eNodeB may send a PDSCH to a specific UE in a specific part of the system bandwidth. The eNodeB may broadcast PSS, SSS, PBCH, PCFICH, and PHICH to all UEs in the coverage area in a broadcast manner. The eNodeB may transmit the PDCCH to a specific UE in the coverage area in a unicast manner. In addition, the eNodeB can also send the PDSCH to a specific UE in the coverage area in a unicast manner.

There can be multiple resource elements available in each symbol period. Each resource element may cover one subcarrier in one symbol period, and each resource element may be used to transmit a modulation symbol, where the modulation symbol may be a real value or a complex value. Resource elements for no reference signals in each symbol period may be arranged into resource element groups (REGs). Each REG can include four resource elements in one symbol period. The PCFICH can occupy four REGs in symbol period 0, where the four REGs are approximately evenly spaced in frequency. The PHICH may occupy three REGs in one or more configurable symbol periods, where the three REGs are spread throughout the frequency. For example, the three REGs for the PHICH may all belong to symbol period 0, or may be extended in symbol periods 0, 1, and 2. The PDCCH may occupy 9, 18, 32, or 64 REGs in the first M symbol periods, where these REGs are selected from available REGs. For the PDCCH, only certain combinations of REGs are allowed.

The UE can know the specific REG for PHICH and PCFICH. The UE may search for a combination of different REGs for the PDCCH. In general, the number of combinations searched is less than the number of allowed combinations for the PDCCH. The eNodeB may send a PDCCH to the UE in any combination that the UE will perform the search.

The UE may be located within the coverage area of multiple eNodeBs. One of these eNodeBs can be selected to serve the UE. The serving eNodeB can be selected based on various criteria such as received power, path loss, signal to noise ratio (SNR), and the like.

The downlink signals from modulator/demodulator 9321-t can be transmitted via antenna 9341-t, respectively.

At UE 920, UE antenna 9521-r may receive downlink signals from base station 910 and provide the received signals to a UE modulator/demodulator (MOD/DEMOD) 9541-r, respectively. Each modulator/demodulator 954 can condition (e.g., filter, amplify, downconvert, and digitize) the respective received signals to obtain input samples. Each of the UE modulators/demodulators 954 may further process these input samples (e.g., for OFDM, etc.) to obtain received symbols. The UE MIMO detector 956 can obtain received symbols from all UE modulator/demodulators 9541-r, perform MIMO detection (if any) on the received symbols, and provide detected symbols. UE receive processor 958 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 920 to UE data slot 960, and provide decoded information to UE controller/processor 980. Control information.

On the uplink, at UE 920, UE transmit processor 964 can receive (e.g., for PUSCH) material from UE data source 962, and receive (e.g., for PUCCH) control from UE controller/processor 980. Information and processing of the data and control information. In addition, UE transmit processor 964 can also generate reference symbols for reference signals. The symbols from the UE transmit processor 964 may be precoded (if any) by the UE TX MIMO processor 966 for further processing by the UE modulator/demodulator 9541-r (eg, for SC-FDM, etc.) ) and sent back to the base station 910. At base station 910, the uplink signal from UE 920 can be received by base station antenna 934, processed by base station modulator/demodulator 932, and detected by base station MIMO detector 936 (if any) The base station receiving processor 938 performs further processing to obtain decoded data and control information transmitted by the UE 920. The base station receive processor 938 can provide the decoded data to the base station data slot 946 and provide the decoded control information to the base station controller/processor 940.

FIG. 9 illustrates an exemplary communication system 1000 for deploying one or more small cells in a network environment. In particular, system 1000 includes a plurality of small cells 1010 (eg, small cells or HNBs 1010A and 1010B) installed in a relatively small scale network environment (eg, one or more user residential areas 1030), where small Cell 1010 can be the same or similar to small cell 110y (Fig. 1) including SON element 130 (Fig. 1). Each small cell 1010 can be coupled to a wireless local area network and/or wide area network 1040 (e.g., the Internet) and via a routing device, cable modem, wireless link, or other connection (not shown). Service provider core network 1050.

As described herein, each small cell 1010 can be configured to service associated access terminals 1020 (each of which can include measurement component 140 (FIG. 1) (eg, access terminal 1020A)), and optionally External access terminal 1020 (e.g., access terminal 1020B), both of which are identical or similar to UE 120 (FIG. 1). In other words, access to the small cell 1010 is limited such that a given access terminal 1020 can be served by a specified set of (eg, home) small cells 1010, but not by any unspecified small cell 1010 (eg, , the small cells of the adjacent point 1010) are served.

A UE (eg, a UE with improved LTE capability) can use a spectrum of up to 20 MHz bandwidth, which is a carrier of up to a total of 100 MHz (5 component carriers) for transmission and reception. Allocated in the aggregate. For wireless communication systems with improved LTE capabilities, two types of carrier aggregation (CA) methods, continuous CA and non-continuous CA, are presented, which are illustrated in Figures 9 and 10, respectively. Continuous CA occurs when multiple available component carriers are adjacent to each other (as shown in Figure 9). In another aspect, a discontinuous CA occurs (as shown in Figure 10) when multiple non-adjacent available component carriers are spaced along the frequency band. It should be understood that any one or more small cells (eg, a network entity) (which includes the small cells 110y shown in FIG. 1) can communicate or facilitate according to the aspects illustrated with reference to FIGS. 10 and 11. Communication with one or more UEs (e.g., UE 120y of Figure 1).

Continuous CA 1070 (Fig. 10) and discontinuous CA 1080 (Fig. 11) may aggregate multiple component carriers to serve a single unit of improved LTE UE. In various examples, a UE operating in a multi-carrier system (also referred to as carrier aggregation) is configured to perform certain functions on multiple carriers (eg, control) on the same carrier (which may be referred to as a "primary carrier") And feedback function) to perform aggregation. The remaining carriers (which depend on the primary carrier used for support) are referred to as "associated secondary carriers." For example, the UE may provide functions such as optional dedicated channel (DCH), unscheduled consent, physical uplink control channel (PUCCH), and/or physical downlink control channel (PDCCH). The control functions are aggregated.

The LTE-A standard may require that the carrier be backward compatible to achieve a smooth transition to the version. However, backward compatibility may require these carriers to continuously transmit a common reference signal (CRS), which may also be referred to as a (cell-specific reference signal) across each subframe of the bandwidth. Most cell site energy consumption is due to power amplifiers, because even when only limited control signal transmissions are sent, the cells remain open, which causes the amplifier to continuously consume energy. CRS is introduced in Release 8 of the LTE standard, which may be referred to as the most basic downlink reference signal of LTE.

For example, the CRS can be sent in the frequency domain and in each resource block in each downlink subframe. The CRS in the cell may correspond to one, two or four corresponding antennas. The remote terminal can use the CRS to estimate the channel for coherent demodulation. The new carrier type can allow the cells to be temporarily turned off by deleting the transmission of the CRSs in the four subframes of the five subframes. This reduces the power consumed by the power amplifier. In addition, the administrative burden and interference from the CRS are also reduced because the CRS is not continuously transmitted in every subframe adjacent to the bandwidth. In addition, the new carrier type may allow operation of the downlink control channel using UE-specific demodulation reference symbols. The new carrier type can be operated as one type of extended carrier along with another LTE/LTE-A carrier, or alternatively as a separate non-backward compatible carrier.
